Explanation

Note: according to Fpsc answer key  the correct  ans is green light

Since the maximum absorption by chlorophyll occurs in red light.

It is the most effective wavelength for photosynthesis.

Chlorophyll strongly absorbs red light.

Thus it is effective at photosynthesis.

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in the presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Explanation

Overcooking can lead to a reduction in the nutritional value of food.

It especially water-soluble vitamins like vitamin C and B vitamins.

As they can be lost in the cooking water or destroyed by heat.

Explanation

• Infrared waves are used in night vision equipment.
• They detect heat emitted by objects.
• It allowing visibility in low-light conditions.

Explanation

Metaphase, one of the most critical stages in mitosis

Chromosomes are most compact in metaphase

When the centromeres of the chromosomes of all cells are aligned with the equator of the mitotic spindle.

Chromosomes are most easily visualized at this stage,

So metaphase is especially useful in cytogenetics.

Explanation

Photosynthesis It is the process of the preparation of food by plants in presence of sunlight.

Oxygen is released in the process and not required for it.

Following reaction takes place during the reaction.

6CO2 + 6H20 + light → C6H12O6 + O2

Explanation

The cell wall is the outer covering of a cell, present adjacent to the cell membrane, which is also called the plasma membrane.

As mentioned earlier, the cell wall is present in all plant cells, fungi, bacteria, algae, and some archaea.

Explanation

Platelets are produced from very large bone marrow cells called megakaryocytes.

As megakaryocytes develop into giant cells,

they undergo a process of fragmentation that results in the release of over 1,000 platelets per megakaryocyte.

Explanation

Roots are food storage organs and hence food is transported to them from the leaves.

Hence roots are sinks.

Also, all young growing parts are considered as sinks as they have the highest rate of metabolism and hence require food.

Developing fruits and the apical meristem are growing parts, and hence act as sinks.

Explanation

ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups.

These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
